wifi: ipw2200: fix memory leak in ipw_wdev_init()
[ Upstream commit 9fe21dc626117fb44a8eb393713a86a620128ce3 ]
In the error path of ipw_wdev_init(), exception value is returned, and
the memory applied for in the function is not released. Also the memory
is not released in ipw_pci_probe(). As a result, memory leakage occurs.
So memory release needs to be added to the error path of ipw_wdev_init().
Fixes: a3caa99e6c68 ("libipw: initiate cfg80211 API conversion (v2)")
